Depending on circumstances it can be done remotely in different ways AFAIK using things like IMSI Catchers, malicious and sometimes invisible SMS messages, and maybe spearfishing or other methods. Or a combination of things, leveraging different weaknesses of the phone in question.

And because this could just enable government bodies to fuck around with spying, that's why usually you have to get a warrant for this kinda stuff on the grounds of probable cause.

This is much much harder though, and would risk exposing the vulnerabilities they are using, so they likely won't use these methods unless it's higher profile and involves some higher up govt entities. Your normal street crime cop shop won't be able to do this.
